You should always follow lane markings, which are there for two reasons they make the best possible use of road space they guide the traffic. Keeping to the lane markings is vital. Position yourself in good time If you find you're in the wrong lane, don't try to change by cutting across other drivers at the last moment. Carry on in your lane and find another way back to your route.
Changing lanes Position your vehicle according to your route. Always check your mirrors and signal in good time before you change lanes.
- Never weave from lane to lane.
- Never straddle two lanes.
- Never change lanes at the last minute.
- Always stay in the middle of your lane
- until you need to change.
In heavy and slow-moving traffic Don't change lanes suddenly keep changing lanes straddle lanes or lane markings weave in and out obstruct 'Keep Clear' markings Watch out for these in congested, slow-moving traffic, especially at exits for emergency vehicles.
- pedestrians crossing
- cyclists moving up the nearside
- large vehicles needing to straddle lanes
- before turning
- doors opening
Driving ahead Keep to the left-hand lane wherever possible Don't use the right-hand lane just because you're travelling at speed. On a carriageway with four or more lanes, don't use the lanes on the right unless signs or markings allow you to do so. Peak hour 'tidal flow' systems might permit or forbid use of these lanes, depending on the time of day. Bus and cycle lanes These are separate lanes shown by signs and road markings Do not enter these lanes unless permitted by the signs.
Approaching a road junction
look well ahead for signs and markings. If you have two lanes in your direction and you intend to turn left, stay in the left- hand lane you intend to go straight ahead, stay in the left-hand lane unless otherwise indicated you intend to turn right, move to the right-hand lane in good time. Don't try to gain an advantage by using an incorrect lane. Trying to change back to the proper lane at, or near, the junction is a I isky business. IT you have three lanes in your direction and you intend to turn left, stay in the left-hand lane go straight ahead, take the left-hand lane (unless there are left filter signs) or the middle lane, or be guided by road markings turn right, take the right-hand lane.
Some junctions also have a slip road. Get into the left-hand lane in good time before entering the slip road. You'll be able to slow down to turn left without holding up other traffic.
